The hearings that had been expected to wrap up Thursday resumed Friday after examiners heard testimony until 11:45 p.m. Thursday, commission spokeswoman DeDe Webb said.

The hearings related to an unauthorized walkout in September in which employees expressed anger about pay rates and working conditions at the Amarillo IBP beef plant. Both employees and IBP had appealed rulings in the case, in which IBP fired more than 500 workers after they failed to return to the plant for scheduled shifts.

IBP eventually rehired some workers on a case-by-case basis. On Thursday, hearing officers took testimony from employers and the primary witnesses from employees, Webb said.
